Electrochemical Treatment of Wastewater of Veterinary Industry Containing Antibiotics

On the performance of a hybrid process to mineralize the herbicide tebuthiuron using a DSA® anode and UVC light: A mechanistic study

“…The photolysis of these compounds by UVC radiation is also possible [25] through the decomposition of previously excited organic molecules, or reaction with reactive oxygen species [26,27], to its intermediates or to CO 2 . The main negative points of this combined process, which is commonly denominated as "photo-assisted electrochemical process", are the high electrical energy consumption caused by the use of high pressure UV lamps [28], low fluency rate, low ratio of anatase to rutile crystalline phases in the DSA ® anode (leading to poor efficiency in the electron/hole pair formation), and possible formation of organochlorine compounds (aromatic or short chain carboxylic acids) [29,30]. All these features have led to uncertainties regarding the electrical energy efficiency of the process and its environmental safety.…”

Advanced Treatment of Coal Chemical Industry Wastewater by Electro-Catalysis with Gd-Doped Ti/SnO2 Anode

“…As an advanced oxidation process (AOP), electro-catalysis has shown great advantages in terms of wastewater treatment, such as satisfactory treatment effect, no derivative pollution and easy automation that is not attached to other technologies [5][6]. Electrochemical advanced oxidation processes (EAOPs) have received great attention for water remediation, especially in the degradation of recalcitrant organic compounds, because they can generate large amounts of hydroxyl radicals (·OH) for an effective and fast mineralization of toxic and hazardous organic contaminants [7][8].…”
